I don't think this is correct.  For example, I used the "times" package
(see my other reply) in a latex source file, generated a DVI file, then
used dvipdf to create a PDF.  Looking at the font information inside
Acrobat reader indicates that, indeed, Type 1 PS fonts are being used.
If math symbols are used, there will be a Type 3 font for that, but this
font too can be replaced by a PS font (see my other reply).

I don't think it's so much a matter of *Acrobat* being able to deal with them,
it's probably a matter of the printer and the print driver dealing with them.
I have generated many PDF files over the years using latex and dvipdf,
and Acrobat handles them fine--I've been able to print them just fine (using
Acrobat) on lots of different platforms and to lots of different printers.

This is a good idea.  Acrobat can also be used to check the font information,
given the PDF file.  pdflatex is a front-end to pdftex, which is distinct from
dvipdf; dvipdf is just a front-end to dvips.

I have to mention that only *PS* printers and associated drivers should be
expected to handle such output "perfectly."  Even then, there are problems
(e.g., MS-word-generated PS files often do not print on my Lexmark T612,
a very standard PS printer).  also, pslatex is a short script front-end to
latex. if the "times" package is being used, pslatex shouldn't make a
difference in the end problem.
